The Chihuahua Dwarf Crayfish
was once thought to live only in a single spring (Ojo de Carbonera in the
state of Chihuahua / Mexico), but was later found in three other springs
within 3 km of the typus locality.

The reasons for its extinction are the same as in Alvarez's Dwarf
Crayfish (Cambarellus alvarezi): pumping of groundwater for
agriculture and thus the complete destruction of the ponds in which the crayfish
species was living in.

~~~~~~~~~~~~~~~~~~~~~

The agricultural industry in this region itself has in the meantime
collapsed - owing to a lack of groundwater!
